I am using the example of the song "More Than Words" by Extreme to illustrate my question.

Cm being used in the same line (line 9). I was unaware of the theory behind this. I have come across a "Picardy Third" in some music before, and that concept somewhat makes sense to me. But I don't think a "Picardy Third" applies here, or maybe I just can't see it.
In addition to this usage of the IV and iv chord, the song also uses the chords
G7. This usage of both the I and I7 chords doesn't make sense to me either, because the key of the song looks to be in
I would appreciate it if anyone can explain this to me.
